49ers PFF grades: Best and worst grades from Week 3 win over Cardinals

The San Francisco 49ers took on the Arizona Cardinals on Sunday for a Week 3 battle at Levi's Stadium, and Kyle Shanahan's team earned a 16-15 win off a last-second made field goal from kicker Eddy Piñeiro.

San Francisco played far from their best game on Sunday, but they also were without several key players and lost defensive end Nick Bosa early in the contest. Still, with a strong defensive effort and a respectable two-minute drive from Mac Jones, the 49ers moved to 3-0 on the season and claimed sole possession of first place in the NFC West.
